A Selective Discontinuous Galerkin Implicit Particle-In-Cell Method For Plasma Simulation With Improved Interpolation, Siyu Wu, Yang Li, Hongtao Liu, Xiaoming He, Yong Cao

Mathematics and Statistics Faculty Research & Creative Works

This article dynamically incorporates multiple ideas into the existing direct implicit particle-in-cell (DIPIC) method for plasma simulation, in order to dramatically improve the DIPIC method for its local mesh refinement needs based on Cartesian meshes as well as its interpolation needs based on the locally refined meshes. One key tool is to utilize the selective discontinuous Galerkin method, which is based on the interior penalty discontinuous Galerkin formulation and the regular local finite element basis functions, as the electric field solver in the DIPIC simulation. This hybrid type finite element method combines the advantages of both continuous and discontinuous finite …

Based on the layered materials of MXene, researchers have successfully achieved the dual functions of energy storage and …

Money For Nothin’, Gifts For Free: The Supreme Court Differentiates Between Bribes And Gratuities In Snyder V. United States, Seth Lewis

Mercer Law Review

The Supreme Court of the United States determined that the federal bribery statute regarding state and local officials did not include gratuities in Snyder v. United States. In Snyder, James Snyder was convicted of accepting an illegal gratuity under 18 U.S.C. § 666 and appealed his conviction. The Court’s decision addressed the split in the United States Courts of Appeals regarding whether 18 U.S.C. § 666 criminalized gratuities, payments made after an official’s act without a prior agreement, along with bribes, payments made with a prior agreement. The Court held that 18 U.S.C. § 666 only criminalized bribes and did …

Coastal Erosion As A Major Sediment Source In The Inner Gulf Of Thailand: Implications For Carbon Dynamics In Tropical Coastal Ocean Systems, Bingbing Wei, Stephanie Kusch, Till J.J. Hanebuth, Limin Hu, Miao Fan, Guodong Jia, Gesine Mollenhauer, Moritz Holtappels

Marine Science

Coastal erosion is an increasingly dominant sediment source in marginal seas, particularly in low-lying areas affected by deltaic subsidence and sediment deficits from upstream water management. However, its role in sediment and organic carbon (OC) dynamics remains to be estimated. Our analyses of the inner Gulf of Thailand (IGoT) revealed that riverine sediment fluxes decreased from 6.6 to 5.4 Mt/yr after 1975, while sediment accumulation within the IGoT increased from 20.8 to 29.5 Mt/yr. The observed trend indicates major sediment contributions from coastal erosion, particularly from mangrove deposits. This process destabilizes coastal ecosystems and accelerates OC decomposition, that is, a …

Three-Dimensional Melamine Carbon Sponge/Nai As Cathode Materials For Sodium-Ion Batteries, Qian-Ying Huang, Yue Liu, Zi-Xin Lin, Shu-Yi Zheng, Ting-Ting Mei, Yu-Ting Tang, Ying-He Zhang, Jun Liu

Journal of Electrochemistry

The sodium-iodine (Na-I) battery exhibits significant potential as an alternative energy storage device to the lithium-ion battery. However, its development is hindered by inadequate electrical and thermal stability, as well as the dissolution and shuttling of polyiodide. In this study, we report a preparation method for melamine carbon sponge (MC) via carbonizing a commercially available kitchen sponge. It was revealed that the as-prepared MC, composed of unique self-growing carbon nanotubes, could provide both physical and chemical adsorption capabilities for intermediate polyiodides to improve the electrochemical performance of NaI. Consequently, the NaI/MC electrode effectively minimized polyiodide dissolution and reduced the electrochemical …

Comprehensive Risk Assessment Of Power Grids Using Fuzzy Bayesian Networks Through Expert Elicitation: A Technical Analysis, Yasir Mahmood, Nof Yasir, Nita Yodo, Ying Huang, Di Wu, Roy A. Mccann

Electrical Engineering and Computer Science Faculty Publications and Presentations

Power grid infrastructures, essential to modern societies for electricity distribution, are prone to vulnerabilities due to their numerous sensitive components, necessitating a comprehensive risk assessment. Uncertainty in historical failure data often compromises accurate risk quantification, leading to the integration of expert elicitation as a solution. This study develops a Bayesian network (BN) risk assessment model integrated with fuzzy set theory (FST), referred to as the fuzzy Bayesian network (FBN). By incorporating expert insights, this model quantifies internal and external risk variables more comprehensively. Crisp probabilities (CPr), derived from regional transmission operator (RTO) failure incident data, are complemented by fuzzy probabilities …

Mechanical Engineering and Materials Science Independent Study

An understanding of tire behavior is crucial to designing a Formula SAE racecar. What variables affect a tire’s performance? How can complex behaviors be modeled mathematically and evaluated with a computer? In this study, data for the Hoosier 16” x 7.5 – 10 R20 tire was analyzed and fit to a Pacejka Magic Formula model, then compared to the WashU Formula SAE team’s current tire (Hoosier 18” x 7.5 – 10) to evaluate the feasibility of switching to a smaller diameter tire. Possible advantages include significant weight savings and a reduction in rotational inertia; however, many other aspects of the …

Understanding The Morphology And Mass Transport Resistance Of Mesoporous Carbon-Supported Pemfc Based On Modeling Analysis, Hao Deng, Jia Liu, Zhong-Jun Hou

Journal of Electrochemistry

Mesoporous carbon supports mitigate Pt sulfonic poisoning through nanopore-confined Pt deposition, yet their morphological impacts on oxygen transport remain unclear. This study integrates carbon support morphology simulation with an enhanced agglomerate model to establish a mathematical framework elucidating pore evolution, Pt utilization, and oxygen transport in catalyst layers. Results demonstrate dominant local mass transport resistance governed by three factors: (1) active site density dictating oxygen flux; (2) ionomer film thickness defining shortest transport path; (3) ionomer-to-Pt surface area ratio modulating practical pathway length. At low ionomer-to-carbon (I/C) ratios, limited active sites elevate resistance (Factor 1 dominant). Higher I/C ratios improve …

The White Elephant In The Classroom: Using Local History And Resource Pedagogies To Remove It, Dawn N. Colquitt-Anderson

Graduate Doctoral Dissertations

Years of scholarship outline the benefits of asset-based pedagogy for all students, especially the culturally and linguistically diverse students who are now the majority student population in public schools. But there is scant research on how experienced in-service teachers modify their practices and beliefs to adequately prepare these students for 21st century leadership. This sequential mixed methods case study examined the efforts of elementary and middle school teachers as they grappled with personal, professional, and systemic barriers that arose as they worked to strengthen their cultural and community responsiveness by centering the local history of a historic great migration town.

Large-Scale Groundwater System Characterization Using Pressure Responses To Barometric Perturbations Caused By The 2022 Hunga Tonga-Hunga Ha'apai Volcanic Eruption, Anhua He, Yang Liu, Fan Zhang, Huamei Zhang, Ramesh P. Singh, Yanzhang Wang

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Hunga Tonga-Hunga Ha'apai volcanic erupted on 15 January 2022, causing Lamb waves to propagate throughout the global troposphere. However, reports on volcanic eruptions–pressure fluctuations and water level dynamics are lacking. We quantified the propagation processes of Lamb waves induced by the Tonga volcanic eruption. Barometric pressure data collected at 1-min intervals at 485 meteorological stations in China showed that the eruption induced an atmospheric pressure event with an amplitude of ∼2 hPa over an hour and a wave speed of 295 m/s. Concomitant groundwater levels were available at 338 wells to find the barometric response to the volcanic event. The …
